Abstract: 1279724 Apparatus for cutting tobacco AMF Inc. 22 Oct 1969 [28 Oct 1968] 51681/69 Heading A4C [Also in Division A2] In a machine for making cigarettes, an endless band of reconstituted tobacco sheet T is continuously shredded by a slitting device 30 into a plurality of substantially endless strands which are then fed by a non-porous conveyer belt 52 under a cover 74 where they are blown laterally across the belt 52 against a guide rail 60, aided by suction applied through a line of apertures 58 in the belt 52, to form a twisted braid of tobacco strands which are then wrapped and cut into cigarettes. The slitting device 30 comprises a plurality of adjustable rotating knives 62 mounted on a common shaft 64 and abutting fixed ledger blades 68. The sheet T.is carried on a bobbin 28 which may be driven via its axle 70 at a variable speed to accommodate its decreasing diameter, via its circumference, or preferably, for bobbins not greater than 22 inches in diameter, merely by the action of the slitting device 30 in pulling the sheet T from the bobbin. The belt 52 runs over a table 26 the upper surface 42 of which, in the area beneath the line of apertures 58, is made of wire mesh or open framework 40, and the lower surface 44 of the table 26 is connected by ductwork 56 to a suction source. In another embodiment, Fig.2 (not shown), a wide tobacco sheet is fed directly from a sheet making apparatus, slit into narrow bands (38) and each individual band (38) is then fed directly to the slitter 30 of a separate one of a plurality of cigarette-making machines of the kind above described.

Title: Magnetic thickness gauges
IPC: H01F7/02
Filed: 1971-11-08
Abstract: 1324459 Measuring thickness magnetically ELEKTROPHYSIK HANS NIX & DRING E STEINGROEVER KG 8 Nov 1971 [7 Nov 1970] 51796/71 Heading G1N In a magnetic thickness gauge of the type wherein the thickness to be measured is a function of the attractive force exerted by a permanent magnet the permanent magnet is composed of anisotropic magnetic material. An elongate permanent magnet connected to a spring balance arrangement has one end, hemispherically shaped, positioned at right angles to a magnetic layer or a non-magnetic layer on a magnetic base being measured. If the magnet is not at right angles to the layer the orientation of the magnetic particles of the magnet are at an angle to the axis of the magnet but due to the anisotropy of the magnet there will be no residual displacement cf the orientation of the magnetic particles when the magnet is subsequently positioned at right angles to the layer and no compensation therefore is necessary, the flux lines again concentrating around the central axis of the magnet. Suitable magnetic materials are specified for tie permanent magnet.

Abstract: 1,165,574. Knitting: finishing fabrics. CLARENCE L. MEYERS & CO. Inc. 29 Nov., 1966, No. 53426/66. Headings D1K, D1S and D1W. In a method of making knitted fabrics, e.g. socks or outerwear, cotton yarns are given s or z twist and are mercerized and retwisted before being interknit, the fabric then being preshrunk. The yarns are given a twist in the single of 2.2 to 5.5 x #S turns per inch, where S is the cotton yarn number, and may be plied with yarns of like or opposite twist. Plied yarns are twisted in either direction within the range 1 to 8 #S/N turns where N is the number of plies. The yarn is then mercerized in a 15% to 20% solution at a temperature of between 70 and 130‹F. The yarn is then retwisted in either direction, but preferably in the same direction as the ply twist, within the range of 0.5 to 5 x #S/N turns to alter the extent but not the direction of the twist. The yarns are then loosely knit with s and z yarns in alternate courses or groups of courses. The fabric is pre-shrunk, prior to dyeing, either by warm washing, or tumble drying to reorientate the stitches preferably at an above-ambient temperature. After dyeing the fabric is boarded.

Abstract: 1,217,672. Multiplex pulse code signalling. GENERAL ELECTRIC, and ENGLISH ELECTRIC COMPANIES Ltd. 2 Feb., 1968 [1 Dec., 1966], No. 53879/66. Heading H4L. In a P.C.M. communication system for twoway signalling, each station has a local oscillator which controls the repetition frequency of the transmitted pulse signal and a phase-locking control system for the oscillator which operates in dependence upon a comparison of a signal derived from the received pulse signal with a signal derived from the oscillator the two signals having nominally the same frequency which is a submultiple of the frequency of the oscillator. Fig. 1 shows a system, not incorporating the invention, in which two exchanges 1, 2 are linked 3, 4 for two-way P.C.M. speech signals, the transit times of the paths 3 and 4 being shown as delays 13, 14. Each exchange has a bit-frequency oscillator 5 from which timing signals for coding, decoding, multiplexing and demultiplexing are derived at 6. The incoming bit frequency is derived at 11 and compared with the output of oscillator 5 in a phase comparator 12 whose -output controls the frequency of oscillator 5. The invention provides a modification, Fig. 2, in which the comparison at 12 is made at the frame rate derived at 19 from the incoming signal and the frame rate also is derived at 21 from the incoming signal and supplied to a further phase comparator 20 where it is compared with the output of oscillator 5 divided at 17 to the frame rate. The output of the comparator 20 adjusts a variable delay line 18 which alternatively may be placed in the outgoing line. In a further modification Fig. 3 (not shown) the incoming signals are supplied to a buffer store from which they are read subsequently, and variable delay line is replaced by a monstable circuit which is voltage-controlled to vary the duration of its output pulses to provide a variable time delay.

One preferred method of oxidation is by means of a peroxide in the liquid phase at 20-200‹ C. Many specific peroxides are listed including hydrogen peroxide, inorganic peroxides, e.g. metal peroxides, peroxy acids or peroxy salts, and organic peroxides, e.g. hydroperoxides, dialkyl peroxides, peroxy acids and peroxy esters. The oxidation may alternatively be effected by an oxygen-containing gas at 100- 500‹ C. or by potassium permanganate or sodium dichromate. The reduction may be effected by hydrogen, ammonia, hydrazine, carbon, carbon monoxide, a lower alkane or a lower alkanol.

A data store is coupled to a processing unit with a plurality of multiplexing circuits each coupled to an associated group of lines having substantially equal data rates. The store includes a plurality of storage areas each allocated to a corresponding one of the multiplexing circuits for storing control words and data. The control unit includes a plurality of index registers, each connected to control reading/writing or data from/to a single corresponding area of this store, the index registers being linked to determine sequence of read out of control information to sequentially enable multiplexing circuits and line connections for the transfer of data between lines and a store. To initiate transmission through an interface, say 11, central processing unit 1 loads control information into unit 2, also a number of line control words one for each line 30 to be used, into buffer 3. The control word for the particular interface 11 is then transferred to group 0 of store 4 which also receives information controlling transmission of data from unit 2 and processor 1, all of which having been assembled is then transferred via store 3 to group 1; this is then applied in sequence to OR 5 which addresses and activates unit 6 also provides a line address along 35 through unit 6 and thence to interface 11; data is then passed along route 30. Data can also be received simultaneously through high speed interface 23 into serial/ parallel unit 9 and thence into group 4 and subsequently through group 0 into CPU 1, the path being set by programme. To avoid conflict, data flow is multiplexed by control unit 2 into time slots, e.g. 5 in number each directed by a micro-programme, typical sequences being illustrated in Fig. 4 (not shown). Transmission circuits of similar format, e.g. low speed, non-synchronous, high speed synchronous, are grouped on to common multiplexers, e.g. six, one for each group. Circuit arrangements to perform the various operations are given in the specification.
